Quad Bias Driver for GaAs FET and PIN Diode Switches
Description
The MADRMA0001 family of quad bias drivers
can either be configured to translate TTL signals into the nega-
tive voltages required for GaAs FET switches or attenuators or they
can be used to produce up to ± 40 mA per channel for biasing series
or shunt PIN diode switches. Each channel contains Inverting and
Non-Inverting Outputs for logic flexibility. Designed with high-speed
CMOS technology, the drivers achieve high performance with very
low power dissipation.

The input logic voltage (V in) cannot exceed the positive supply (Vcc) by more than 0.5 V nor go be-
low GND by more than 0.5 V.
The input current should not exceed ± 25 mA.
This device should be treated as any TTL CMOS circuit. Pull-up/down resistors should tie to Vcc or
GND. Non-used inputs must be tied to GND. Decoupling caps (0.1 uF) should be used on Vcc and
Vee, and the output current should be limited to ± 40 mA.
Logic “0” sets J0 to J1 to low loss state
Limiting Resistors (R2, R3) set for +/- 20 mA output current
The value of the limiting resistors (R2, R3) is determined by the following: R1 = [(Vcc - Vdiode)/I de-
sired] - Rout
